To all 'whom it may concern.-

Be it known that I, JAMES R. RHEUBOT- TOM, of Weedsport, New York, have invented an Improved Safety Chain-Lock, for securing valises, &c., in railway-cars, and for other purposes, of which the following is a specification in form, as shown in Fig. 1, and consists of al ca se composed of three parts, A and G, and the cap B, Figs. 2 and 3, to one of which, A, is attached the side casin g G, through which two openings, a and b, Fig. 2, are made for the passage of the chain. The case and cap are fastened together by the pin c, Figs. 1 and 3, passing through the center of the case, and riveted on the outside, in such manner that the two cases may revolve freely and independently of each other, the casing A C turning within the milled edge of the cap B. The pin c extends through from one side to the other, and forms a spindle, (shown in dotted lines d, Fig. 3,) rigidly attached to the cap B. The chain D is secured at one end to the spindle c, about which it is wound. To the other end of the chain is fastened a hook, e, Figs. 1 and 3. The ratchet E, Fig. 3, is secured to the cap B by the spindle e, and revolves with it.

When the catch e is introduced into the opening a of the casing it engages with a tooth of the ratchet E, and, sliding underneathi the side of the casing, (see Fig. 1,) is held in place by it, and prevents the case om turning in one direction, while the ratchet E, upon being locked, prevents the case from turning in the other direction. The locking device by which the ratchet E is fastened is shown in Fig. 4. A recess is formed in the face of the ratchet E, (shown by dotted lines in Fig. 3,) and into this recess project the teeth of the interior ratchet F. A catch, G, sliding between the pin a and the guide f, which is attached to the case A, engages with the teeth of the ratchet F under the pressure of the spring g, which is also attached to the case A.

A key, h, Fig. 2, introduced into the opening in case A, provided for it, (see Fig. 1,) on being turned, presses against the curved end of the catch Gr, and holds it in the position shown in dotted lines in Fig. 4, in which case the ratchet F is detached, and the case A is free to turn.

When the catch e is removed from the opening in the casing, the cap B, to which the ratchets are attached, can then be revolved in either direction, and the chain D wound upon or unwound from the spindle c.

When the proper length of chain is secured, the catch e is introduced into the opening in the casing C, and the key being removed, and the cases slightly rotated upon each other, the catch G engages with the ratchet F, and each end of the chain is then securely fastened within the lock.

A flexible metallic strap or band may be used in place of the chain D.

The pieces A and B may be fastened to'- gether, and the ratchets and spindle arranged to revolve within the case by means of a button or crank attached to the outer end of the spindle c.

In a modified form of my device I have used a smaller ratchet, with teeth on its exterior, attached to the ratchet E, in place of the ratchet F, the locking arrangement being correspondingly modiiied, and adapted to operate on the exterior of the smaller ratchet.

Ihe operation of the parts is entirely the same, the case, however, being slightly thicker.

I have now explained my invention, and described the manner of putting it into practical operation which I prefer to adopt; but it is obvious that many alterations may be made therein without materially changing the prin# ciple thereof. Thus, one ratchet or equivalent device may be made to do the work of the two herein described, and it may be attached directly to one` or the other of the cases, a suitable spring-catch being so arranged upon the, other case. as to perform. they tWo-func i Lingof. a ratchet and a springfcatch, arranged -.tions of holding the end ofv thechain, vand to to bey unlocked by a keyfsubstantiaily as deprevent the rotation of the cases upon each scribed.
